Data Encoding
In the point-to-point configuration, the IPAC supports both NRZ and NRZI data encoding
(selectable via CCR1 register).

NRZ Encoding/NRZI Encoding
During NRZI encoding, level changes are interpreted as log 0, and no changes in level
as log 1.
Data output on the IOM interface is performed with the rising edge of DCL, data input
with the second falling DCL clock edge.
